SPECZFICATION forming part of Letters Patent No. 398,251, dated February 19, 1889.

Application filed November 24, 1888- Serial No. 291,728. (No nioileld To all 10700720 it may concern: pose of securing the work-holder to said hol- Be it known that I, HENRI L.

In one piece with the headstock l), or so 35 a is ahand lover or crank secured to orformcured to it in a suitable manner, is a bracket, ing a part of the pinion a; and it will thus g, in which is journaled the spindle h, that. is be seen that by taking hold of the said lever capable of a longitudinal adjustment in said or handle and swinging it to the right or left bracket. To the said spindle his secured the a corresponding movement is imparted to the block '1', preferably by means of a set-screw,

The forward end of the cured a crank or hand wheel, 75, by means of hollow shaft 0 is externally screw-threaded, which said screw-shaft is manipulated. Thus 50 and to it is screwed the chuck (Z, for the purit will be seen that a longitudinal motion is imparted to the spindle h by turning the screw-shaft 7t around'its axis.

To the rear end of the spindle h is secured by means of a set-screw, Z, the lever l, the end of which is forked, as shown at Z in Figs. 1, 2, and 3. Said forked end of the leverl is made to fit between flanges or collars on the nut m, that is adjustable on the screwthreaded end on" of the spindle m, that passes loosely through the hollow spindle c and shank e of the expansive work-holder e; and to the forward end of said spindle on, within the slitted work -holder e, is secured the circular disk or block 011 which, when moved backward within the expansive work-holder, causes itto expand and to hold the watch-case f securely attached to the outer edge of said expansive W01"l(-l10l(l61, as shown in Figs. 1 and 2. It will thus be seen that by the device above mentioned the slitted work-holder can be expanded for the purpose stated simply byturning the screw-shaft 7c in one direction. For the purpose of coinpressing the said work-holder in case itis desired to hold a watch case or ring on the inside of the work-holder, I secure to the opposite end of the longitudinally-adjustable spindle h a second lever, 01, having a forked and grooved end, a, adapted to hold and receix e a ring, a", that surrounds the slitted tapering work-holder e, as shown in Figs. 1, 2, and 4. Consequently by moving the spindle it toward the right in Fig. 1 the ring n" will be moved toward the larger end of the workholder 6, and thereby causing the latter to be contracted for the purpose mentioned.

The lever n is preferably secured to the spindle h by means of a set-screw, n (Shown in Figs. 1 and 4.)

If it is desired to expand the work-holder e for the purpose of securing the work against the outer edge of said work-holder, I loosen the setscrew n sufficiently to liberate the lever a and swing it upward around the spindle h, so as to cause it to be disconnected from the ring it". If it is desired to compress or clamp the work within the work-holder, I secure the lever n in position 011 the spindle h, as shown in Figs. 1, 2, and 4, and unloosen the set-screw Z and swing the lever Z upward around the spindle h, so as to cause it to be disconnected from the flanged nut m.

In shaping successively a number of watch cases or rings of the same size and pattern, it is important that the work-holder should be expanded or contracted equally for the successive pieces that are to be shaped and in such a manner and degree as to hold the article firmly without injuring it, and for this purpose I use,in connection with the scrcw-shaft 7c and its block i, an indicator for the purpose of showing at a glance when the screw-shaft 7; has been turned around sufficiently to cause the work-holder to properly hold the work, after such movement of the said screw-shaft has first been ascertained, for the desired article. Said indicator is constructed as follows: To the block 2 is secured a rack, o, the teeth of which mesh in the teeth of the pinion p, that is journaled on the pin 19, secured in a suitable manner to the bracket q. The said bracket (1 is secured to the bracket 9, as shown in Fig. 3. To the bracket (1 is secured the graduated dial, q, and to the pinion p is secured the index finger or pointer p". (Shown in Figs. 1, 2, and

If it has been ascertained that to properly secure a certain size watch case or ring to the expansive worc-holder e the screw has to be turned so as to cause the pointer p" to indicate, for instance, 6 on the dial q, then all the operator has to do in securing successive watch cases or rings to the work-holder is to turn the screw-shaft kuntil the fin ger 19 points to 6 on the graduated dial q after the watch case or ring has been placed outside or inside of the expansive work-holder e, as the case may be.

For the purpose of limiting the forwardand-back motion of the head-stock b and its connections, I employ stops, as follows: To the rear end of the head-stock b is secured a bracket, 1), through the lower rear end of which is screwed the adjustable stop-screw Z), as shown in Figs. 2 and The outer and lower portion of said bracket is preferably slitted, as shown in Fig. 3, and provided with a clamping-screw, l)", for the purpose of securing the said stop-screw in position on the bracket Z) after such screw has been adjusted. To the end of the bed a is pivoted on a bolt or pin, a, the circular disk a provided with a series of rearwardly-projecting setscrews, a (L as shown in Figs. 2 and 3. By turning said disk a around its axis either of the said set-screws can be brought opposite and centrally in a line with the stop-screw 11 so as to prevent the head-stock 1), its workholder, and the article held by it from being moved farther forward toward the tools when the screw 1) is brought in contact with that one of the set-screws a that is for the time being opposite to said stop-screw b and in this manner the forward movement of the head-stock is regulated and limited.

a is a spring-pressed pin located in a recess in the end of the bed a and adapted to be forced into one of a series of recesses on the forward side of the disk a, as shown in Fig. 2.

In connection with the head-stock and its work-holder I use a series of tools hereinafter to be described, said tools being so arranged as to act successively on the article to be shaped; and it is for this purpose that I use a series of adjustable sot-screws, a arranged on the rotary disk a, so that one of said stopscrews can be easily brought opposite to the head-stock stop-screw I)" simply by turning the disk a slightly around its axis according to the feed desired on the head-stock for the corresponding tool.

For the purpose of limiting the sliding motion of the head-stock in the opposite direction I secure to the side of it a pin or projection, a", which as the head-stock is moved backward comes in contact with one of a series of regulatin stop-screws, r r, adjustalfly secured to the disk r, that is pivoted to a bracket, 0, secured to the bed a, as shown in. Figs. 1, 2, and 3. p s s 5 represent the tool-posts, havingseeured to them the respective shaping-tools s s s by means of set-screws ,or equivalent devices. The tool-posts s s s are firmly secured to the tool-carrier 2, that is mounted in dovetailed guides on the tool-carrier bed 11 and is laterally movable thereon at a right angle to the motion of the head-stock b, as shown in the d rawi n gs.

The tool-carrier bed u is adjustable'to and from the work-holder e, and is for this purpose guided on ways a a on the bed a, and

is secured to the latter after being adjusted by means of the screw-bolt a, cross bar or plate at, and nut a or similar devices. The tool-carrier and its tool-holders are moved forward and back. on the bed to by means of a hand-lever, r, that is pivoted at u to an arm or projection, 21, on the bed a, and the said lever is connected to the tool-carrier t by means of a link, r. (Shown in Figs. 1 and i.)

For shaping the edge or circumference of the watch case or ring f, I prefer to use an additional tool-post, S, having a tool, S, secured to it, as shown in Figs. 1, 2, 3, and 4c. Said tool-post is secured to the tool-post carrier t by means of a bolt or pin, S, passing through said tool-post and a perforation, t, in the carrier '15 and secured to the latter by means of a nut, S (Shown in Figs. 2 and 4..)

In using the tool S the bed it is moved toward the right end of the bed at until said tool comes opposite, or nearly so, to the edge or circumference of the article that is to be shaped, and said bed a is then secured to the bed a in such desired position, after which the tool-carrier t is moved by the hand-lever 7; until the tool S is brought in contact with the edge or other portion of the article to be shaped.

One tool-post S is only shown in the drawings; but provision is made in the bed If for holding two such toolposts, as shown in Fig 1.

The tools 5 s s are to be of varying shapes for the purpose of shaping different parts of the article. For instance, one tool may be adapted for shaping the article near its edge or circumference, another for the central portion, and others for shaping intervening portions between the center and circumference, as may be desired, according to the form or pattern to be given to the said article. It is also essential in a machine of this kind that adjustable stops should be provided on the tool-carrier 2, so as to cause the desired tool or tools to be moved to the desired positions relative to the article that is to be shaped, and for this purpose I secure to the said toolcarrier t a pair of screw-threaded shafts or spindles, If if", one located above the other and both provided with adjustable stop-nuts 15 it, as shown in Figs. 1, 2, and 4.

To the bed to is secured a bracket, n, and to said bracket is pivoted at n a pair of levers, a 11 each having notched projections a u, adapted to embrace one or the other of the respective screw-shafts i if, and it will thus be seen that by adjusting the respective nuts 25 according to the position desired for the respective tools 3 s, and by swinging the stop-levers a against the screw-shafts t" if, the desired tool will be brought to a stop in the desired position for doing the desired work when the toolcarrier is operated by means of the lever '12.

The operation of the shaping-machine is as follows: The article to, be shaped is secured to the expansive work-holder 6, either on its outside or inside, as described. The shaft 0 is set in a rotary motion by belt-power applied to the cone-pulley c, and the operator takes hold of the lever r with one hand and moves the tool-carrier t on the bedu until one of the tools 3' is brought to the required position for doing the desired shaping of the article, as described, after which the operator moves the head-stock 1) toward the right in Fig. 2 by manipulating the crank or lever 0, thereby causing the revolving watch case or ring to be brought in contact with the shaping-tool that is being used, and thereby causing the desired portion of the article to be given the form corresponding to that of the tool that is used. The sliding movement of the headstock is limited by the stop mechanism hereinbefore mentioned. After a por tion of the article has been shaped by one tool, the head-stock Z) is moved backward, another tool brought in position, and the headstock again moved forward, and so on. until the article is properly shaped. In using the tool S on the tool-post S the bed u is secured to the bed a, so that the tool comes about opposite to the edge of the article to be shaped. The head-stock Z) is held in a corresponding position, and its shaft 0 is rotated, as before, after which the tool-carrier t is moved by means of the lever c until the tool is brought to the desired position for doing the shaping, and so on.

The operation of the machine may, however, be varid according to the work to be done without departing from the essence of my invention.

I-Iavin g thus full y described the nature, con-- struction, and operation of my invention, I wish to secure by Letters Patent and claim- 1.
